kevin Posted September 29, 2020 Report Share Posted September 29, 2020 Hi overhauling my front brake PB Metric callipers. I have split the calipers to enable easier removal of seized pistons. The caliper repair kits on sale do not appear to contain the small O-rings that seal the two halves of the assembled caliper. The rationale I believe is the two halves should not split? I therefore need to source the two small O-rings made from silicon or Viton but not pure Nitrile, does anybody know who supplies them? Looking at general o ring kits as a last option, as getting the correct OD, ID and thickness is clearly important to achieving the correct seal and getting the right combination of dimensions and material is not as easy as it sounds.

kevin Posted September 29, 2020 Author Report Share Posted September 29, 2020 Thanks Colin, I also rang TD Fitchetts who also sell them as “bridge seals” Link to comment Share on other sites More sharing options...
Gully Posted September 30, 2020 Report Share Posted September 30, 2020 I bought them from Moss (Europe) Ltd. Think the postage cost more than the o-rings! Gully Link to comment Share on other sites More sharing options...
